LG 77-Inch Class OLED evo AI vs TCL 85-Inch Class QM8K Series QD

Design and build quality

The LG 77-Inch Class OLED evo AI focuses on a sleek profile suitable for various lighting conditions. LG highlights that this model is Verified by UL for Discomfort Glare Free, achieving a UGR less than 22. This certification suggests the unit is designed to perform consistently regardless of room lighting, maintaining perfect black levels that contrast sharply with brighter environments. The design philosophy centers on minimizing distraction to enhance the viewing experience.

In contrast, the TCL 85-Inch Class QM8K Series QD utilizes a CRYSTGLOW WHVA Panel with an anti-reflective edge-to-edge ZeroBorder. TCL notes that the ZeroBorder refers to the hardly perceived BM zone at the edge of the image under normal viewing scenes. This design choice aims to deliver vibrant colors and crisp detail from every angle, ensuring that the physical bezel does not intrude on the immersive quality of the 85-inch display.

Display Technology

LG employs its flagship OLED technology, celebrating 12 years of development. The screen utilizes 8.3 million self-lit pixels, which allows for individual pixel control. This technology is fundamental to creating perfect black levels, as pixels can turn off completely rather than relying on a backlight. The OLED evo panel is paired with Brightness Booster technology, which magnifies each individual pixel for luminous quality.

TCL utilizes QD-MINI LED technology, described as a premium level Mini LED TV. This system incorporates the New TCL Halo Control System. The technology suite includes a Super High Energy LED Microchip and Condensed Micro Lens. Additionally, it features Micro-OD Reduced Optical Distance and a High Contrast HVA Panel. This combination is engineered to provide stunning images while managing light distribution differently than OLED.

Picture Performance

Picture quality on the LG model relies on the Alpha 9 AI Processor Gen8. This processor handles AI Super Upscaling technology, which automatically enhances picture quality across sports, movies, and other content. The self-lit pixels ensure that perfect black and perfect color are maintained, delivering a watching experience that aims to match stellar standards set by the brand's OLED history.

The TCL model focuses on achieving Halo-Free images through its Dynamic Light Algorithm and Bi-direction 23-bit Backlight Controller. The Zero Delay Transient Response is part of the HALO Control System, ensuring that motion and contrast transitions are handled without visible artifacts. The Enhanced QLED layer contributes to color vibrancy, complementing the high contrast HVA panel for a distinct visual signature compared to OLED.

Audio Capabilities

Audio implementation differs significantly between the two units. The LG TV relies on internal processing powered by the Alpha 9 AI Processor Gen8 to deliver sound that matches the picture quality. While the brand states everything sounds incredible on their OLED TVs, specific external audio hardware details are not highlighted in the provided data.

TCL includes a 7.1.4 Channel Q Class Sound Bar with the TV. This system is designed to fill the room with sound, bringing a movie theater experience into the home using just a single HDMI cable. The system supports Dolby Atmos and DTS:X for spatial sound. This inclusion simplifies home theater setup by providing dedicated hardware for audio reproduction rather than relying solely on built-in speakers.

Processing and AI Features

The LG Alpha 9 AI Processor Gen8 acts as the brains behind the TV experience. It is responsible for personalized smooth and vivid pictures regardless of the content source. The AI capabilities extend to upscaling, ensuring that lower resolution content looks improved on the high-resolution panel. This processing power is central to the brand's promise of an unforgettable TV experience.

TCL counters with the TCL HALO Control System, an advanced technology suite. This includes the New Super High Energy LED Microchip and a Dynamic Light Algorithm. These components work together to manage backlighting and color processing. The focus here is on controlling light precision to ensure stunning viewing experiences without halo effects around bright objects on dark backgrounds.

Connectivity and Ports

Specific port counts such as HDMI or USB quantities are not specified in the provided data for either model. However, TCL mentions that the included sound bar connects via a single HDMI cable, indicating HDMI eARC or similar functionality is present to facilitate audio return. This simplifies the connection process for the external audio system.

LG does not explicitly detail port configurations in the provided text. Users should verify specific connectivity needs such as HDMI 2.1 for gaming or multiple inputs for peripherals based on official documentation beyond this summary. Both units are modern televisions expected to support standard connectivity required for streaming devices and consoles.

Price and Value

The LG 77-Inch Class OLED evo AI is priced at $1699.99. This price point positions it as a more accessible option for users seeking OLED technology. The value proposition is strengthened by the inclusion of verified glare-free technology and the reputation of the Alpha 9 processor. For buyers prioritizing picture contrast and budget efficiency, this model presents a compelling case.

The TCL 85-Inch Class QM8K Series QD is priced at $2981.44. This higher cost reflects the larger 85-inch screen size and the inclusion of the 7.1.4 Channel Q Class Sound Bar. When considering the cost of a separate sound system and the premium for Mini LED technology at this size, the value proposition shifts toward users who want an all-in-one home theater solution without purchasing separate audio components.

Which one should you buy?

Choosing between these two televisions depends on prioritizing screen size and audio versus cost and contrast. If you require the largest possible screen and want an integrated sound system, the TCL 85-Inch Class QM8K Series is the superior choice. The included 7.1.4 Channel Sound Bar and Dolby Atmos support provide immediate audio upgrades, and the 85-inch QD-MINI LED panel offers high brightness.

If you prefer perfect black levels and want to save over $1000, the LG 77-Inch Class OLED evo AI is the better option. The 8.3 million self-lit pixels provide contrast that Mini LED struggles to match, and the UL Verified glare reduction ensures usability in bright rooms. For movie watchers who prioritize image fidelity over raw size and bundled audio, the LG model delivers higher value.
